AF Spotbeam projector
When the shutter release button halfway down
where it is hard for autofocus to work, such as in a
dark place, the built-in flash discharges continu-
ously to provide illumination, making it easy for the
autofous to work.
• The effective range of AF spotbeam projector is
approx. 1m to 5m.
• The AF soptbeam of the built-in flash does not
work if you use the soptbeam of the external
flash such as the AF500FTZ or AF330FTZ flash.
• The AF spotbeam does not work either when the
Action Program Mode has been selected with
the focus mode switch set to the MF position or
when the flash disable mode has been selected.
• The external flash discharges if the AF spot-
beam works when the AF500FTZ is attached
and the slave flash function is in use.You should
therefore set the focus mode switch to the MF
position before using the slave function.
Red-eye Reduction Flash Function
This camera includes a red-eye reduction flash
function, which reduces the red-eye phenomenon
utilizing preflash. In this mode, the preflash is dis-
charged just before the shutter is released which
reduces the diameter of the pupil of the eye. Then
the main flash is discharged while the pupils are
smaller, which in turn reduces the red-eye effect.
About Red-eye Phenomenon
Shooting portraits with flash in a dark environment
often causes a subject’s eyes to turn out reddish
in the print. This phenomenon, commonly known
as “Red-Eye”, is caused by the reflection of the
electronic flash in the retina of your subjects eye.
It can be reduced by taking the photo in a brighter
light condition or by shooting with a wider angle
lens at a closer distance, or by employing the red-
eye reduction flash feature. When using a Pentax
dedicated flash unit off the camera, it may also
help to position the flash as far away from the
camera as possible.
